I am trying to solve a mystery. We have 2 replicated FreeIPA servers.
Today they both stopped receiving requests because the Directory Server
had begun to refuse connections.
The relevant message is "Not listening for new connections - too many
That's all well and good: I can increase the file descriptor allowance.
However, the reason the fds limit was reached was a massive number of
connections from the servers themselves.
Can someone provide me with an idea for what this might be?
We received 1024 connections in under 1 second: Here is an example
dirsrv access log entry:
[22/Oct/2009:12:29:53 +0200] conn=679021 fd=464 slot=464 connection from
127.0.0.1 to 127.0.0.1
[22/Oct/2009:12:29:53 +0200] conn=679021 op=0 BIND
24,dc=net" method=128 version=3
[22/Oct/2009:12:29:53 +0200] conn=679021 op=0 RESULT err=0 tag=97
nentries=0 etime=0 dn="uid=kdc,cn=
Some final notes:
Both servers stopped one after the other. First server A, then 1 second
afterwards, server B.
I'm pretty stuck as to what might have caused this.
